Abstract (en)
[origin: WO2018027261A1] A transmitter of a DFT-based communications system including an orthogonal precoder for transforming modulated data symbols using a unitary transform, wherein the data 5 symbols are mapped to subcarriers of the transmitter and the computational complexity of the transform is linear with respect to the number of the subcarriers.
